data
interface. It provides the capability to display 262,144 colors
(18-bit color) with a large dynamic output range for twisted
nematic applications. When used in a bank with other
FPD33584 column drivers, the FPD33584 can support XGA
(8 drivers) or SXGA (10 drivers) applications. Output volt-
ages are gamma corrected to provide a direct mapping
between digital video and LCD panel brightness. The 85MHz
operating frequency allows the FPD33584 to meet the re-
quirement of high refresh rate applications (i.e. XGA moni-
tors with a 75Hz refresh rate).
An RSDS (Reduced Swing Differential Signaling) interface is
used between the timing controller and the column driver to
minimize EMI and reduce power.
